i have them on mine, they work great for my aging eyes. I have installed them on others who have seen mine and then they wanted them. I was out shooting one day when a tactical shooting team was there and they were looking into getting them but doubted their agency would spring for them. The lead trainer bought a pair and I installed them for him on his personal weapon. they wanted to put them on their mini 14 rifles and were calling the company about it. I have tried various other sights and these work the best for me. but then thats just me.

I have them on my G31 and like them. They work very well once you get use to them. I've played with varied front post sight pictures and can reliably hit targets at 100yrs after some practice. Mine are zeroed for 25yrds and hit about 2-3" lower at 50yrd. Not as easy to use as my Dawson adjustable rear but still work good for my intended use.

I have been looking for a sight I can use for duty carry and competition. My concern with most fiver optic sights is durability. Are these sights durable enough for daily carry?

I know there are some police forces that use it. The only big knock against it at this time is No night sights. That should change in November this year, they are supposed to release their Firefly option. That can fit into their existing system and be a glow in the dark option. I believe the owner told me 90 seconds of light on the sights will last 7-8 hours and 10 seconds would last for an 1 hr ~ from a tactical light. Any other ambient light they recharge. That will make them more attractive for LEO. So I'm looking forward to that option.

I have them on my two primary carry guns (M&P 9c and G29). Have used them for years in a leather pancake holster. No wear that I can see, and they still hit POA. They have proven to be very durable, for me.
